  • APPARATUS AND METHOD FOR COMMUNICATION BETWEEN DOWNHOLE COMPONENTS
    Publication number: 20140192621
    Abstract: A method of synchronization between downhole components includes: generating a dual tone synchronization signal by a signal generator in a first downhole component disposed in a borehole in an earth formation, the dual tone signal including a first constituent periodic signal having a first frequency f1 and a second constituent periodic signal having a second frequency f2 that is different from the first frequency; transmitting the synchronization signal to a second downhole component disposed in the borehole; receiving the synchronization signal by a signal processor in the second downhole component, calculating a phase difference between the first constituent signal and the second constituent signal, and calculating a transmission delay based on the phase difference; and synchronizing operation of the first and second downhole components based on the delay.

  • Color-neutral UV blocking coating for plastic lens
    Patent number: 5949518
    Abstract: Polymeric coatings containing both UV absorbers and dyes are employed to produce transparent, durable film coatings that can significantly increase the level of UV radiation blockage when coated onto substrates including ophthalmic lenses. The dye comprises 1-?(4-methylphenyl)amino!-4-hydroxy-9, 10-anthracenedione. The color-neutral film coatings are resistant to weather and UV degradation.
